Top Fuel 9.8 XT Gen 4 is a lightweight carbon trail bike built to rip up climbs and stay playful on descents.

It gives you the confidence you want through roots and rocks, thanks to a 120mm/130mm RockShox suspension package with a Pike Select+ fork and Deluxe Ultimate shock.

Plus, you get clean shifts from a 12-speed Shimano XT drivetrain.

  • Top Fuel Gen 4 delivers with an intensely lightweight build, improved in-frame storage, and more adjustability for all kinds of rides and riders

  • With 120mm rear and 130mm front RockShox suspension, it delivers a well-balanced ride that stays efficient on the ups and playful on descents

  • The 4-way Mino Link makes it easy to adjust your geometry or leverage rate for how and where you want to ride

  • In-frame storage with an improved BITS bag system makes it easy to stash tools, tubes, and snacks

  • It's more upgrade-ready than ever, with room for bigger 140mm forks and longer-stroke shocks for up to 130mm of rear travel, plus room for extra-long dropper posts

Carry-On, But For Your Bike

Top Fuel’s new storage system is easier to use with a bigger opening, more secure seal, and all-new BITS bag system. Carry your essentials on your bike, not your body.

Room For Bigger Suspension And Longer Dropper Post

Top Fuel Gen 4 is more upgrade-ready than ever, with room for bigger 140mm forks and longer-stroke shocks for up to 130mm of rear travel, plus room for extra-long dropper posts.

Tubeless Tires

All Trek Checkpoint ALR, SL and SLR models come tubeless out of the box. Sealant, valves, and rim stips included.

Ditching the tubes and going tubeless will help you get the most performance out of your tires. There are no tubes to pinch, so you can run lower pressures for better traction, and you get more control and a smoother, faster ride. As an added bonus, a tubeless setup can help seal punctures before they become flats.
